Abstract

Abstract In nitroxide-mediated radical polymerization, the polymerization times decrease with the increasing re-formation rate constant of the C [BOND] ON bond ([RIGHTWARDS ARROW] alkoxyamine) between the growing polymer chain and the nitroxide radical. The factors influencing the re-formation rate constant are of considerable interest, but up to now, the polar/stabilization effects have not been addressed thoroughly. The combination of ...
